Helicopter fire injuring occupant, sequela

This code signifies a long-term health condition or complication arising from an injury sustained by an occupant in a helicopter fire. It indicates that the initial injury event occurred in the past, and the patient is now presenting for treatment of the residual effects or sequelae of that original incident.

This code is appropriate when a patient is being treated for a chronic condition, scar tissue, functional impairment, or other lasting consequence directly attributable to an injury suffered during a helicopter fire. It should be used for follow-up encounters after the acute phase of the original injury has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., burn scar, chronic pain).
• Ensure documentation clearly links the current condition to the past helicopter fire event.
• The "S" in the 7th character indicates sequela; do not use for initial or subsequent encounters for the acute injury.
